[Bilateral renal angiomyolipoma associated with tuberous sclerosis: conservative surgical treatment]. / Angiomiolipomas renales bilaterales asociados a la esclerosis tuberosa: tratamiento quirúrgico conservador.

OBJECTIVES: To evaluate the efficacy of surgical treatment of angiomyolipoma. METHODS: We present a case of multiple, bilateral renal angiomyolipoma in a patient with tuberous sclerosis, who was treated by conservative surgery. RESULTS: The patient is clinically asymptomatic one year after surgery and both kidneys are functioning correctly as shown by pyelography. CONCLUSIONS: We recommend conservative surgical treatment of symptomatic or developing angiomyolipomas.

[Cutaneous metastasis of epithelioid sarcoma of the penis: report of a case]. / Metástasis cutánea de un sarcoma epitelioide de pene: a propósito de un caso.

Exposition of one case of skin metastasis in a 35 year-old patient, diagnosed 10 years previously with epithelioid sarcoma of the penis, which was treated with total penectomy. The singularity of this case lies in the rarity of a pineal site for this tumour, as well as the infrequency of the skin metastasis. It should be noted the significance of long-term follow-up in this patients, since quite frequently they develop metastasis following a long asymptomatic period.

[Giant hydronephrosis: conservative treatment by endopyelotomy]. / Hidronefrosis gigante: tratamiento conservador mediante endopielotomía.

A case of giant hydronephrosis in the right kidney and inferior pelvis of the left kidney in a 60-years-old female patient with nonspecific abdominal symptoms and signs is reported. Because involvement was bilateral and the patient insisted on conservative treatment, we performed a bilateral percutaneous endopyelotomy. The excellent results achieved were demonstrated by ultrasound. This however was not true for the functional results due to the irreversible renal lesion.
